However, Jerry Crasnick of ESPN reported later in the day that Jennings has a clause in his contract that allows him to interview for the Mets job.
Jennings doesn't need Marlins' permission to interview w/several clubs. Mets are one of the teams on his list. source JCrasnick Twitter
There's not much out there on Jennings, even the Marlins site doesn't have a bio page on him. Basically from what I can gather he's considered to be from the scouting side of things and is credited with many of the low budget jewels the Marlins have found. Way back in 2003 BA considered him a top candidate to become a GM ( #2) but why he hasn't in all that time is unknown...
Jennings didn't take long to establish a reputation as a respected talent evaluator. He spent two years as an associate scout with the Reds before earning a full-time scouting job with the Mariners in 1988. Just seven years later Jennings was hired as the first scouting director in Devil Rays history. Despite losing several premium picks as compensation for free-agent signings, he helped stock the system with a string of impressive drafts from 1997-2002 that netted Aubrey Huff, Carl Crawford, Rocco Baldelli, B.J. Upton, Joey Gathright and Dewon Brazelton. Jennings left Tampa Bay for his current position following the 2002 draft and played an instrumental part in guiding the Marlins to the 2003 World Series. Fellow Marlins execs Jim Fleming and Mike Hill also received strong support as strong GM prospects. source BAThat still leaves several questions; are the Marlins trying to block the interview, are the Mets interested in more then one Florida executive and if his current employer doesn't want him to interview, will he anyway.
